My invention relates to improvements in shut-od nozzles for lire hoseuse, and the like; and its principal objects are, first, to provide arotary ball valve, so constructed and adjusted as not to come in`contact with the outer casing of thenozzle except at its axis, andprovide an open space around the ball for safety and for a water jacket,whereby the shut-olf valve is made to turn on and oli' more easily thanhas been possible heretofore, and accumulation of sand and other debrisin the valve is avoidedgjsecondly, to provide improvedmeaiis fordirecting the flow of water thru the nozzle, to prevent vibration andill the water jacket; thirdly, to provide an open space for said waterjacket between the outer casing of the nozzle and the shut-ofi' valvewhereby danger of rendering the valve of the nozzle inoperative bydeliting, bending or other external injury by falling ,onv hard.surfaces is lessened; fourthly, to provide an adjustable and removablevalve seat on opposite sides of the ball valve, each adapted to fit overa segment of the globular surface around the orifice of' the ball, oneseat fitted to seal the water passage thru the nozzle, and the other toconcentrate the stream and also fill the water jacket; and fifthly, toprovide improved means for reseating and evenly grinding and polishingthe valve. seats.

It consists broadly of the novel construction and'combination ofelements for accomplishing said objects and other kindred features, ashereinafter fully set forth and stated in the appended claims.

My invention is illustrated by the accompanying 'drawing in whichsimilar letters and figures indicate like parts. Referring thereto, Fig.1 is a side view of the valveportion of the hose nozzle, partly cut awayalong one side thereof to show the interior mechanism when the valveball 1s turned to shut-off position; and Fig.. 2 is a longitudinalsection of the same, showing the ball valve turned to open position, andthe means for adjusting the pressure on the ball to make" the valvewater tight. Fig. 3 is a side view of the hose nozzle valve case. Fig. 4is a perspective view of Fig. 1 drawn on a 1927. Serial No. 195,510.

reduced scale. In the drawings, A indicates the outer casing or bodyportion of the shutoff nozzle, B, the valve rotary ball having a centralaperture b equal in diameter to the bore of the nozzle which is to bejoined thereto on the helical threaded end a, The ball is mounted on atransverse shaft S, which is operable externally by the handle F, asshown in Fig. 1, the shaft being mounted for rocking in bearings in thevalve body A, and in a threaded plate H, and adjustably secured and madewater tight by means of a gasket I, which is held under pressure of thethreaded nut f around the shaft, as shown in Fig. 2. A short adjustabletube C is fitted 05 over the ball center, and this tube may be readilyremoved by the removal 'of the threaded short sleeve D.

Resilient pressure may be made on the ball seat by means of a gasket Ewhich intervenes between the upper end of the tube C and the lower endof the threadedl sleeve D, and thus makes the joint between the ball andtube water tight, and the ball to be easily turned by the handle F. Hoseconnection is made i with the valve body by means of the threaded end ain the usual Way; and the stream of water is graduall concentrated anddirected thru the orifice in the ball, by a tubular member G securedimmediately below the U ball within the body A, as shown in thedrawings. Said tubular member is adjustably mounted in the casing A,below the ball valve B, and extends upwardly a short distance into thewater jacket aforesaid and so as to SJ surround a segment of the ballwhich is aligned with the orifice therethru, and is adjustably held inrelative position within the casing walls so as to normally restrloosely against the adjacent surface of thel vball valve, without beingwater tight.`

It is sloped from within outwardly for the purpose of 'concentrating theini'iowing "stream into the smaller orifice of the nozzle withoutvibration, and also supplying the water jacket by the inflowingstreamauto- A-matically. If preferred the terminus of the tubular memberG, may be made to register exactly with the concavity of the ball, butthe suicient infiow to fill the water jacket. By said means the streamof water flows unob structedly thru the nozzle orifice without jarringor vibrating the nozzle.

The lower end of the tubular member C may be -made `concave and groundto it snugly upon the globular surface of the ball B, so that when thelatter is turned to shutof/ position, ,as in B', Fig. 1, there can be no1o water leakage thru the nozzle; and when turned to open position, asat B, Fig. 2, the tubular member fits closely around the oriice b in theball, as shown by the dotted lines around the latter. Wear of the jointbetween the ball and said tubular member C may be com nsated andthejoint adjustably tightene or loosened by means of the threaded sleeve D;and the gasket E may thus be pressed 'outwardly between the slopingedges 4of said tube and sleeve,so as to prevent leakage between s aidmembers; and by the rey moval of both of said members and the yieldablegasket E, the surface of the ball may be reground, and the co-actingtubular members re-fitted at pleasure.

I am aware it is not new to provide a r0- tary valve in shut-olfnozzles, and such -I do not broadly claims But what I claim as new and,desire to se- 1.
